Hi-Fi Amplifier

The Hi-Fi amplifier is designed as an analogue two-channel amplifier with an output power of 2x40 W. The Hi-Fi amplifier is connected via two channels to the M-ASK. The input signals are amplified via integrated band filters and bridge-type output stages to 2x40 W and output to the central woofers.

The control takes place via the M-ASK. Due to the distribution of the output stages in the M-ASK and in the Hi-Fi amplifier, the output stages must be switched on/off synchronously. The time required to switch on the output stages must not exceed 25 ms to ensure no crackling or clicking noise is heard.

The Hi-Fi amplifier does not feature diagnostic capabilities.

The Hi-Fi amplifier is installed on the rear left in the luggage compartment.
